Reuters has published an excellent primer on biodiesel and ethanol.

Collectively called ‘biofuel’, the two are the most well-known alternative fuel sources for vehicles.

Did you know, for example, that the U.S. is the second largest maker of biodiesel? Brazil, using its massive crops of sugarcane, is the largest producer. The South American country already mixes twenty-five percent ethanol with its gasoline and is seeking more markets to export its surplus.

The Philippine government is supporting efforts for biofuel development using coconut oil.

Ethanol is currently mixed with gasoline to reduce emissions.
